T 0 all Lofi-0m t may concerf/t Be it known that I, LIONEL M. WooLsoN, a citizen of the United States, and resident of Detroit, lVayne County, State of Michigan, have invented certain new and useful vlinuorovements in Hydrocarbon Motors, of which the following is a specification.

This invention relates to hydrocarbon motors, and particularly to means for heating the mixture passing to the motor.

Une of the objects of the invention is 'to `lu-ovide means for heating the mixture of a hydrocarbon motor before it enters the cylinders and before a charge is fired in any 0f the cylinders.

Another object of the invention is to proride means for compressing and firing a small amount of combustible mixture in a closed space and then delivering the burnt pas to the motor intake conduit for heatingr the mixture as it passes therethrough.

Other objects and advantages will appear from the following description taken inconnection with the drawing which forms a partof this specification, andin mich the figure shows a portion of4 a hydrocarbon motor and parts thereof embodying this invention. f'

Referring to the drawing, 10 indicates a fragmentary ,portion of one of the cylinder blocks of a hydrocarbon motor, and 11 is the motor intake conduit or passage through which the mixture passes to the motor cylinders. The conduit 11 is shown as of elbow formand to its down turned end is connected a carburetor 12,'which may be of any desired form or. typclMThe arlmrctor supplies mixture to the conduit/1l through which it is conveyed to the motor. The cr; buretor also has as a part of it', .a rfloat chamber 13 of the usual type.

Means are provided for supplying heat to the mixture as it passes from the carburetor 12 through the intake conduit 11 of the motor and in general this means comprises a cylinder 14 and a piston 15 operating therein. As shown, this cylinder 14; is formed as an integral part of the casting forming the conduit 11 and it has an inlet port 16 at'one ort 17 at the opposite side, the outlet port )eing slightly above ne inlet ort and exhausting the burnt into a jacket 18 formed around a part of the intake conduit`1l. A port 19 connerie the interior of the jacket 18 with the interior of the intake conduit llabove a throttle ralve20 arranged in said conduit 11. Thus the suction of the motor above the throttle valve 2O is communicated to the 'jacket 18 and consequently to the interior of the cylinder 14 when the piston 15 is low enough to open the port 17. The piston l5 has a defiector or baille 2l formed on its upper surface to deflect the incoming gases to the upper part of the cylinder so that they will not pass directly across .the top of the piston to the opposite port 17. i spark plug 22 is provided in the upper part of the cylinder', and it understood that it may be connected to the ignition system of the motor sol that a spark is intermittently formed in the cylinder as the piston reaches the upper end of its stroke. if desired, the compression space in the cylinder may be -made sufficiently small so that the charge will be automatically fired at the top of the-stroke due to high compression, and, in this case, the spark plug may be omitted. y

For delivering a mixture to the cylinder 14, the port 1G may be connected either with the carburetor 12 below the throttle Valve 2() or it" may beconnected to 'a separate and independently actingl carburetor 23, which is v'shown as'mounted on top of the fioat chamber 13 above referred to. A pipe 24 carries the mixture from the auxiliary carburetor 23 to the port 16.

The piston 15 :drove referred to may be operated in various ways. and it is shown as connected by a rod a rock shaft 26 and a llink Q7 with an eccentric 28 on a rorating shaft 29. The shaft 29 may be the cum shaft or other rotating part of the hydrocarbon motor, or it may be the armatureV shaft of an electric motor, which electric. motor may also be the starting motor of the hydrocarbon motor. In the latter event, the timing mechanism for the spark plug 22 will be connected to the electric motor for operating the spark in time with the reciprocations of the piston 15.

From the above description it will be seen that as the hydrocarbon motor is i turuedover for starting, suction will be lcreated in the intake pipe or conduit 1l.,

and if the throttle valve 20 is only slightly opened, a small amount of mixture will be drawn from the carburetor 12 and. pass thlsyugh the conduit 11 to 'the motor cyiindcrs. @taires-.sion will also be created in tee leoltet i8 nd the Pi reeeteci by the l liytifooebon moto moto?. is the pi ont oi? its i ine epiession in the jeelet nient the depression in the e this Wiil conse suction tiii'oug i me pipe 24, tiieieby drawing e. eli-enge et' combustible mixture i'iozn. the eiixilieiy carburetor This @beige ot mixture drawn into the eyiindei ifi above the piston lo will be coin .ottoni iines, wii nog pressed Within the oyiincieil es the piston moves upwardly, and when. the piston is at the top of its stroke, the charge will be fired by the spark plug The piston i5 then moves downwacdij/ and uncoveis the pont 1T and the het gases ioni tile cyl indei' pese into the jacke-.i118 and thereby heet the intake conduit il.

it will be apparent that changes may be made Without departing from the Spirit oi* scope ot the invention.
